BRICK WALL CONS-TRUCTION Filed Jan. 51, 1924 2 Sheets-Sheet 2 FIG. 6.

Patented Apr. 1 1930 UNITED STATES PATENT OFFICE WILLIAM C. HECKEROTH, OF ERIE, PENNSYLVANIA, ASSIGNOR TO ERIE CITY IRON WORKS, F ERIE, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA BRICK-WALL CONSTRUCTION Application filed January 31, 1924. Serial No. 689,357.

It is desirable in wall constructions to brace the wall sections, one to another, and to provide air spaces between them. This is particularly useful in furnace walls, or walls subjected to great heat where it is desirable to insulate the lining from the outer wall by an air space and to tie the lining with the outer wall. It is also desirable to form the tying means so that this may be accomplished as the lining is renewed without disturbing the permanent wall. The present invention has for its object the improvement of a wall construction along the lines above suggested. Other features will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follows Fig. 1 is a perspective view of one of the locking members.

Fig. 2 a similar view of a tying member.

Fig. 3 a front elevation of a wall provided with a casing, a part of the casing being removed to better show construction.

Fig. 4 a sectional, or end, view of a wall having a metal casing.

Fig. 5 an end view of a wall having three wall sections.

Fig. 6 is a block forming an open space for the removal of one of the interlocking blocks.

Fig. 7 shows a preferred form of double locking tie block.

Fig. 8 a preferred form of interlocking tie block acting with the block of Fig. 7.

Fig. 9 a tie block corresponding to that shown in Fig. 7 but for a single tie block.

Fig. 10 a plan view of a double wall showing the tie blocks in section.

Fig. 11 a plan view of triple wall, the tie blocks being in section.

Fig. 12 a side elevation of the wall shown in Fig. 10.

Fig. 13 an elevation of the wall shown in Fig. 11.

1 marks a lining, 2 a permanent wall, and 3 a locking block formed in the permanent wall. This is formed of suitable material and as ordinary building tile are formed. It has a base portion 4, acentral upright supporting portion 5 and top 6. It also has an L-shaped groove or channel 7 in one face forming an interlocking lip 8. It has a similar channel 9 in the opposite face and this is closed by a shell 10 where this is at the outer surface of the wall.

A locking block 12 is designed to be laid in the lining 1. It projects across the air space and is provided with a groove 13 which receives the lip S and a projecting lip 14 which interlocks with the lip 8, the block projecting into the channel 7.

1 The bottom surface of the block 3 is ribbed at 11 and the surface of the block 12 is ribbed at 15 so as to assure a tying of these blocks in the wall in which they are set.

The blocks are made of a thickness corresponding to a multiple of the thicknesses of the bricks used so that they can be readily arranged in the wall.

In Fig. 5 I show a second lining 16 and the blocks 17 are similar to the blocks 3 except that the strip 10 is omitted. Blocks 12 are arranged in both linings and engage the lips at opposite sides of the block 3.

In Fig. 4 the wall has a metal casing 18 provided with the usual insulating material 19. This is tied by bolts 20 which have the hooked ends 21 hooked into the channels 9.

In Fig. 10, 22ma-rks the permanent wall and 23 the lining. Tie blocks 24 are arranged in pairs, each having grooves 25 forming inwardly extending locking lips 26. Tie blocks 27 are arranged in the lining 23.

These have the outer faces 28 forming lips 29 which interlock with the lips 26. A space 30 is arranged in the wall above the tie blocks 24 into which .the end of the tie block 27 may be moved when the lining wall 23 is torn down, thus permitting the removal of the tie block 27.

In Fig. 11 there is shown a triple wall having a permanent wall 22 and linings 31 at each side. Tie blocks 32 extend across and project from the permanent wall. These have the hooked ends or interlocking lips 33 and the tube-like tie blocks are arranged with the lips facing each other forming undercut channels. Bricks 34 are built up between the tie blocks 32 and a block 35 is placed on the upper brick 34, the block 35 having a central wall 36 with a top wall 37 and open spaces 38 adjacent to and in line with the space or channels formed between the tie blocks 32. Blocks 27 are arranged in the lining walls and the interlocking lips of the blocks 27 are engaged by the lips 33, thus tying the walls together. hen it is desired to 1' move one of the lining walls the block may be moved upwardly, it then moving into the space 38, thus permitting this movement.

What I claim as new is 1. In a. brick wall construction, the combination of two wall sections; two blocks in one wall section having opposing lips on the blocks inwardly laced with the blocks in place forming an undercut channel; and a block in the opposing wall having outwardly and opposingly faced lips interlocking with the lips forming the channel.

In a brick wall construction, the combination of two wall sections; a tie block construction in one wall section having an undercut channel; and a tie block in the other section having a T-fornled head extending into said channel.

3. In a brick wall construction, the combination of two wall sections; a tie block c0n truction in one wall section having an undercut channel; and a tie block in the other section having a T-forined head extending into said channel, the wall having the undercut channel having an open space permitting the removal of the T-head from the channel.

a. In a brick wall construction, the combination of two wall sections; a tie block construction in one wall section having an undercut channel; a tie block in the other section having a T-for1ned head extending into said channel; and a block in the wall arranged above the channel, said block having an opening in its face in continuation of the channel permitting the removal of the T-head block from the channel.

5. In a brick wall construction, the combination of three wall sections; a tie block in the central wall having locking lips at opposite sides of the wall; and tie blocks in the other sections having projecting lips interlocking with the lips of the tie block in the central section.

6. In a brick wall construction, the combination of three wall sections; a tie block con struction in the central wall section forming undercut channels in the opposite faces of said walls; and tie blocks in the outer walls having T-head ends engaging the undercut channels of the tie block construction of the central wall.

7. In a brick wall construction, the combination of three wall sections; a tie block construction in the central wall comprising two tie blocks having inwardly faced hooks at their ends forming undercut channels; and tie blocks in the outer wall having T-head ends engaging said channels.
